Assessing Traffic and Emergency Benefits of Railroad Grade Separations
(American Society of Civil Engineers, 1987)The benefits of constructing grade separations at four railroad crossings in Thunder Bay, Canada, are evaluated. The purpose of the study is to determine the two crossings whose grade separations provide the most efficient ... -
Optimal Maintenance Decisions for Pavement Management
(American Society of Civil Engineers, 1987)The object of this investigation was to develop a procedure for making optimal maintenance decisions for a deteriorating system. The particular system chosen for study is a pavement, and a methodology is developed to ensure ... -

Traffic Control at Intersection Sites During Reconstruction
(American Society of Civil Engineers, 1987)Microscopic simulation using an efficient microcomputer‐based program is employed in evaluating alternative control strategies for intersections during construction. The program runs on an IBM PC or compatible, is interactive ... -
Incremental Optimization Design of Transit Service
(American Society of Civil Engineers, 1987)An interactive design procedure for the incremental optimization of transit route service is developed based on the concept of elasticity and the total differential. The purpose of this method is to find the set of optimum ... -
Pavement Condition Data Analysis
(American Society of Civil Engineers, 1987)This paper describes a computer methodology for analyzing pavement condition data to define inputs for pavement management systems. This system of programs was developed during a Federal Highway Administration research ... -
XNET: Extended Traffic Assignment Model
(American Society of Civil Engineers, 1987)A PC‐based traffic planning model for use by small cities is described. The software includes routines for estimating OD matrices from observed link data and for determining equilibrium traffic flows. The mathematical ... -
Modal Split Analysis Using Logit Models
(American Society of Civil Engineers, 1987)This study attempts to identify the mode and the factors that contribute to the selection of a particular mode for commodity movements provincially based on average shipment size, control, loads, hire, and type of commodity. ... -
Buried Concrete Pipe Trench Installation Analysis
(American Society of Civil Engineers, 1987)The conventional approach for determining load on buried concrete pipe for trench installation is summarized. A finite element computer model's capabilities are demonstrated by examining cases of trench installations for ... -
Electronic Schedule Display System
(American Society of Civil Engineers, 1987)Riders of local public‐transit systems in many parts of the country do not currently enjoy a schedule display that shows when buses will depart, while almost all air travelers can see when planes leave on such a system. ... -
Flexible Pavement Strains Caused by Auto Tires
(American Society of Civil Engineers, 1987)This paper includes the results of an analytical study of the effects of automobile tire loads on thin asphalt pavements over granular bases. Two different methods of calculating the tire contact pressure are used and the ... -
Network Performance Evaluation Model for HOV Facilities
(American Society of Civil Engineers, 1987)A model to assess the impacts of major high‐occupancy vehicle (HOV) facilities on regional levels of, energy consumption and vehicle air pollution emissions in urban areas is developed and applied. This model can be used ... -
Data Base for Preliminary Cost Estimating
(American Society of Civil Engineers, 1987)Preliminary cost estimates for contracted construction, rehabilitation, and maintenance projects are an important part of a transportation agency's planning and budgeting process. Such cost estimates can be developed through ... -
PC‐Based Traffic Accident Data Analysis Program
(American Society of Civil Engineers, 1987)A menu‐oriented microcomputer database package has been developed to record and analyze traffic accident data in a small‐ to medium‐sized jurisdiction. Designed primarily for the traffic engineer, the package was developed ... -
Microcomputer Tool for Freeway Work Zone Planning and Scheduling
(American Society of Civil Engineers, 1987)Planning and scheduling freeway maintenance and construction activities requires the consideration of tradeoffs between the efficiency of performing the work and the inconvenience to motorists traveling through the work ... -
Bridge Analysis and Rating with Microcomputers
(American Society of Civil Engineers, 1987)A software system is developed to analyze the rate existing bridges. The system is capable of rating simple truss and continuous girder bridges up to three spans. Composite and noncomposite steel girders and concrete T‐beam ... -
Comparison of Computer Programs for Isolated Signalized Intersection
(American Society of Civil Engineers, 1987)The goal of this study is to make a comparative assessment of selected programs developed for traffic signal planning, design, and operation of isolated signalized intersections. A comprehensive inventory is conducted and ...
